Improved catarrhaii syringe



-Huiiml eaaaw ftitfe. a Way intent IMPROVED CATARRHAL SYRINGE.

The Schedule referred to in these Letters Patent and making part of theBa To all whom it may concern:

Be it known that I, J. W. OULBERTSON, of Richmond, in the county ofWayne, and State of Indiana, have invented a newand improved CatarrhalSyringe, for injecting fumes, liquids, or atmospheric air, into thenasal-passages, pharynx, or middle ear; and I do hereby declare that thefollowing is a full and exact description thereof, reference being hadto the accompanying drawings, making a part of this specification.

My'invention relates to an improved construction of the nozzle of asyringe, whereby it is especially adapted to the uses for which it isdesigned; and also, in attaching the nozzle directly to an elastic bag,without the intervention of a flexible tube, thereby rendering theinstrument more convenient, and reducing the cost of its manufacture.

To enable others skilled in the art to make and use my invention, I willproceed to describe the same, with reference to the drawings, in which-Figure 1 is a perspective view of my improved,

syringe. Figure 2 is a longitudinal section of the same, and Figure 3 islikewise a longitudinal section, made at right ang es with the sectionrepresented in fig. 2.

' The nozzle is oval in form,.and is provided with a centralperforation, that emits a single jet, which is protected by theconcavity in the nozzle, as shown by the drawings.

By this arrangement, the jet can be made more penetrating and effectivethan it would otherwise be, thereby peculiarly adapting it to the useshereinafter enumerated.

. The nozzle A is secured directly in the cap E of the elastic bag B,without the intervention of a flexible tube. By means of thisarrangement, the greatest simplicity and durability are combined withconvenience and economy of construction.

The nozzle fills one side of the nostril. Pressing on the other sidewith the finger prevents the escape of whatever is used, and the amountof force required is regulated by compressing the bag.

In this manner the middle car can be inflated.- If the Eustachian tubeis closed, it can be opened by a forcible jet of air from thisinstrument.

By compressing the bag, and plunging the nozzle in solutions, thenasal-passages and pharynx may be flooded and cleansed, and remediesdirectly applied by the patient himself.

Having thus fully described'my said invention,

,What I claim, and desire to secure by Letters Patent, is y The enlargedoval nozzle A, having a central perforation for-the jet, and providedwith a concavity at the end, as and for the purpose'set forth.
